This resulted in multiple estimates for the controls and other statistics (i.e., the constant and the Nagelkerke R square), which are therefore not presented in the table. bThis effect (b) was similar but not statistically significant (p>0.10), when the major life events were analysed simultaneously (i.e., in one model, including all events and control variables, as presented in chapter 2; see table 2.2).
